My question involves paternity law for the State of: Ohio

I would like to remove the fathers name from from my birth certificate. My mother is deceased and I never knew my real father but my mothers husband at the time signed the birth certificate. (I was born in Washington, if that makes a difference) After she died he proved in a court of law he was not my biological father via DNA tests. I'm getting ready to apply for finacial aid for college and am afraid they will not consider me as an independent student if his name is on it. Should I and can I remove his name?
